Calibration of ALIBAVA readout system — •Artur Trofymov for the ATLAS experiment collaboration — DESY, Hamburg, Germany

The High Luminosity Large Hadron Collider (LH-LHC) is the upgrade of the LHC that foreseen to increase the instantaneous luminosity by a factor ten with a total integrated luminosity of 3000 fb⁻¹. The ATLAS experiment will need to build a new tracker to operate in the new severe LH-LHC conditions (increasing detector granularity to cope with much higher channel occupancy, designing radiation-hard sensors and electronics to cope with radiation damage). Charge collection efficiency (CCE) of silicon strip sensors for the new ATLAS tracker can be done with ALIBAVA analog readout system (analog system gives more information about signal from all strips than digital). In this work the preliminary results of ALIBAVA calibration using two different methods (with "source data" and "calibration data") are presented. Calibration constant obtained by these methods is necessary for knowing collected charge on the silicon strip sensors and for having the ability to compare it with measurements done at the test beam.
